Abstract
A flashing for sealing a waterproof roofing membrane to a vertical wall such as a parapet wall around the roof, including an elongated mounting flange for connection to the wall, a top flange and wall flange which define a filler channel with the vertical wall. An elongated elastromeric filler piece is adapted to fit closely within the filler channel with an overlapped portion of the roofing membrane for a temporary adjustable hold on the roofing membrane. A set of finger like tabs preferably punched out of the wall flange may be bent into the filler channel beneath the membrane and filler piece to hold it securely therein. Alternative embodiments for use with pre-existing walls and for attachment to a brick and motar wall at the time of construction are shown, as are corner pieces for sealing inside and outside corners.
